Description Lumír Balhar 2019-08-06 12:49:14 UTC 
Python 2.7 will reach end-of-life in January 2020, over 9 years after it was released. This falls within the Fedora 31 lifetime.
Packages that depend on Python 2 are being switched to Python 3 or removed from Fedora: https://fedoraproject.org/wiki/Changes/F31_Mass_Python_2_Package_Removal#Information_on_Remaining_Packages
Python 2 will be retired in Fedora 32: https://fedoraproject.org/wiki/Changes/RetirePython2

To help planning, we'd like to know the plans for mlt's future. Specifically:


- What is the reason for the Python2 dependency? (Is it software written in Python, or does it just provide Python bindings, or use Python in the build system or test runner?) 

- What are the upstream/community plans/timelines regarding Python 3?

- What is the guidance for porting to Python 3? (Assuming that there is someone who generally knows how to port to Python 3, but doesn't know anything about the particular package, what are the next steps to take?)


This bug is filed semi-automatically, and might not have all the context specific to mlt.
If you need anything from us, or something is unclear, please mention it here.

Thank you.

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to 31.
Comment 2 Lumír Balhar 2019-08-14 09:02:46 UTC 
Please answer the above questions. If you don't the package can be orphaned: https://fedoraproject.org/wiki/Changes/F31_Mass_Python_2_Package_Removal#Information_on_Remaining_Packages

If you need any information or help, please let us know.

Comment 4 Petr Viktorin 2019-08-15 09:24:26 UTC 
Please ask for a FESCo exception for mlt. Mention the upstream plan to "Do Python 3 conversion during 2021."
Here's an example exception request: https://pagure.io/fesco/issue/2208


As far as I can see, mlt requires gtk2, but gtk2's Python2 dependency (in gtk2-devel) is not strongly related to python2-mlt.

Comment 8 Miro Hrončok 2019-09-12 09:46:26 UTC 
Exception granted. I trust that once flowable is updated, we can drop python2-mlt, but I see little benefit in tracking it via this bugzilla. (Reopen as FutureFeature if you disagree.)
